He had already had some experience
in a part of the region to be searched, had been a governor of
Ile-de-France, and during a South Sea voyage had named the cluster of
islands east of Papua now called the D'Entrecasteaux Group. The second
ship was placed under the command of Captain Huon Kermadec. The Huon
River in Tasmania, and the Kermadec Islands, N.E. of New Zealand, are
named after him.
Fleurieu again drew up the instructions, and based them largely upon
the letter from Laperouse quoted above, pointing out that remains of
him would most probably be found in the neighbourhood of coasts which
he had intended to explore. It was especially indicated that there was,
south of New Holland, an immense stretch of coastline so far
utterly unknown. "No navigator has penetrated in that part of the sea;
the reconnaissances and discoveries of the Dutch, the English and the
French commenced at the south of Van Diemen's Land."
Thus, for the second time, was a French navigator directed to explore
the southern coasts of Australia; and had Dentrecasteaux followed the
plan laid down for him he would have forestalled the discoveries of
Grant, Bass and Flinders, just as Laperouse would have done had his
work not been cut short by disaster.
It has to be remembered that the instructions impressed upon
Dentrecasteaux that his business primarily was not geographical
discovery, but to get news of his lost compatriots.
